Two sizes fits all. The "For Web" option is the low resolution image size (500px at 300 DPI). This size is perfect for use on websites, blogs, e-newsletters, etc. The "For Print/Video" option is the high resolution original image size. This sized image can be used for any video or print project, signage or poster project. Also, the "For Print" option can be downsampled for use on the web as well.
